Information Quality and Accessibility

Abstract

This research examines the relationship between information quality dimensions across information quality frameworks. An examination of the literature reveals that several information quality frameworks have been developed in an attempt to measure the phenomenon of information quality. These frameworks consist of information quality dimensions. Current research has placed much emphasis on dimensions such as accuracy, completeness and consistency. However little if any research has been conducted with respect to the consistency of dimension measures across frameworks? The literature also points out that research into conceptual dimensions is limited. This research endeavours to address these shortfalls by examining the accessibility dimension. The research is conducted within the context of information quality frameworks and assessment methodologies. Over the last number of years, access methods to information systems have also evolved. This has resulted in a diverse number of architectures accessing multiple information systems. Much research has concluded that accessibility is an influence on information quality. An experimental research methodology is employed to tackle the research questions. The research to date has examined different information systems’ access methods and their affect upon information quality dimensions. The affect upon other dimensions that make up the information quality framework is measured. The findings to date indicate that the timeliness dimension is most affected. The restriction of access to information systems via web services is also significant.
